Step-up and step-down power supply chip
It is a four switch buck boost DC-DC power management chip. Internally integrated with reference power supply, oscillator, error amplifier, current limiting protection, short circuit protection, half bridge drive and other functions. It can adopt control strategies based on input and output voltage and load conditions, providing stable output within a wide input voltage range (7V-150V), suitable for high current applications such as battery power supply that require voltage rise and fall. It also supports battery charging and has functions such as under voltage protection, over temperature protection, and output short circuit protection. The packaging form is QFN32
